Organic light-emitting device and method for producing an organic light-emitting device

An organic light-emitting device comprising a substrate, a first electrode on the substrate, a first organic functional layer stack on the first electrode, a charge carrier-generating layer stack on the first organic functional layer stack, a second organic functional layer stack on the charge carrier-generating layer stack, and a second electrode on the second organic functional layer stack, wherein the charge carrier-generating layer stack comprises at least one hole-transporting layer, an electron-transporting layer and an intermediate layer, and wherein the at least one intermediate layer comprises a naphthalocyanine derivative, wherein the naphthalocyanine derivative comprises the formula B

• where R1 and R2 can each be selected independently of one another to be the same or different and are selected from a group which comprises hydrogen, alkyl residues and aryl residues or
• where R1 and R2, which are arranged in a meta-position with respect to one another, collectively form an aromatic ring system consisting of one, two or three rings, and
• M1=Co, SnO, VO or TiO.
